ABSTRACT Arctic tundra and boreal forest soils have globally relevant functions that affect atmospheric chemistry and climate, yet the bacterial composition and diversity of these soils have received little study. Serial analysis of ribosomal sequence tags (SARST) and denaturing gradient gel electrophoresis (DGGE) were used to compare composite soil samples taken from boreal and arctic biomes. This study comprises an extensive comparison of geographically distant soil bacterial communities, involving the analysis of 12,850 ribosomal sequence tags from six composite soil samples. Bacterial diversity estimates were greater for undisturbed arctic tundra soil samples than for boreal forest soil samples, with the highest diversity associated with a sample from an extreme northern location (82oN). The lowest diversity estimate was obtained from an arctic soil sample that was disturbed by compaction and sampled from a greater depth. Since samples from the two biomes did not form distinct clusters on the basis of SARST data and DGGE fingerprints, factors other than latitude likely influenced the phylogenetic compositions of these communities. The high number of ribosomal sequences analyzed enabled the identification of possible cosmopolitan and endemic bacterial distributions in particular soils.

Digital information retrieval has been as a problem, and at the same time a research interest for information scientists in recent years. They have planned some solutions to solve problems manifested during the 1990s. Designing meta‐tags and applying them to HTML documents was a remedy in this direction. Meta‐tags can help authors, publishers and indexers of Web pages to analyze intended content more precisely and efficiently. The aim of the present survey is to measure meta‐tags of the Iranian Web sites in accordance with an international criterion. To carry out the research, 346 Iranian Web sites were selected among 3,342, which represented a sample of all Web sites existed in Iranhoo, an Iranian Web directory. The source codes of the sample home pages were reviewed in terms of the presence of keywords and description meta‐tags. The findings of the survey showed that 31.5 percent and 24.6 percent of the Iranian Web sites have keywords and description meta‐tags respectively. The paper concludes that the Iranian Web sites are lower than non‐Iranian Web sites in terms of the use of meta‐tags.

Full textAbstract:
Information linking seed movement, along with changes in seed viability, is critical for understanding weed seed dynamics. Studies were conducted to examine the use of passive integrated transponder (PIT) tags placed in nylon mesh packets in combination with GPS (Global Positioning System) technology to track weed seed movement after tillage. Cylindrical PIT tags 11.5, 12, 20, and 23 mm long by 2 mm wide were evaluated in water and soil. Detection improved as tag size increased because of greater signal strength. Tags with the main axis oriented vertically were recovered at greater depths than when placed horizontally. Average detection depths for 12-mm PIT tags were 29.5 cm in water, 18.2 cm in sand, 24 cm in artificial soil, and 21.2 cm in sandy loam soil. Tests also showed that PIT tags and nylon mesh packets were resilient to intense tillage with a rototiller. No significant differences in displacement because of tillage were observed between free PIT tags and PIT-tagged packets. PIT tag performance was further tested in a 2-yr field experiment conducted between September 2003 and October 2005 at six sites in Nebraska and Wyoming. Tilled and no-till blocks were established at each site. PIT-tagged packets in the tilled block and untagged packets in the no-till block were used. Sample burial depths were 0, 2.5, 7.5, and 15 cm. Sample recovery rate did not differ between tilled and no-till blocks. Time of recovery was the main factor affecting recovery of packets buried at 0 and 2.5 cm in both blocks. Seed predation by small rodents and movement of samples beyond the area of study by tillage implements were the main sources of packet loss. Nevertheless, 2 yr after initiation of the study, more than 85% of the samples were recovered. Future development of PIT tag technology will lead to an enhanced ability to monitor seed movement.

Full textAbstract:
Purpose The purpose of this paper is to explore different tagging behaviours between Chinese and Americans by analysing the movie tags, and explore the feasibility of applying cultural differences to tag recommendations. Design/methodology/approach This paper introduced hypotheses based on several well-established psychological theories and tested them with social tags for the same movies generated by Chinese and Americans. And to prove the utility of the cultural factor consideration, this paper conducted a cross-cultural tag recommendation experiment. Findings The results show that compared with Americans, Chinese users tend to add more tags about movies’ background information (e.g. release year) and global contextual characteristics (e.g. genre); they also prefer to add tags about production countries and factual tags, and cultural factors can be applied for recommending more accurate tags. Research limitations/implications Other reasons for tagging differences beyond cultural factors have not be explored. Tags for some sample movies in MovieLens might be unstable, as they had been tagged by a small scale of users; as a result, the tags’ type distribution might be influenced. Practical implications The results and conclusion of this study will be beneficial for the cross-cultural applications of social tags and mining users’ interests based on tags. Originality/value This paper provided a deeper investigation of the cross-cultural effect in people’s social tagging behaviours from cognitive perspective, and an empirical analysis has been performed to explore proper approaches of incorporating cultural differences for tag recommendation.

Full textAbstract:
AbstractParasites have been used successfully as biological tags in population studies, mainly in marine fishes, but also in marine mammals, crustaceans and molluscs. Almost all published information dealing with parasites as biological tags evaluates differences between localities. However, local variability in the component community has not been assessed. In this work, we examined whether local variation of the metazoan parasite fauna of Engraulis ringens, extracted from five independent samples from two nearby localities in northern Chile, can be a factor causing bias in stock identification. Our results show that local variability, as estimated by a single sample, may suffice to represent component community variability with no need for replicated data.

Full textAbstract:
Mass cytometry (CyTOF) is a critical cell profiling tool in acquiring multiparameter proteome data at the single-cell level. A major challenge in CyTOF analysis is sample-to-sample variance arising from the pipetting process, staining variation, and instrument sensitivity. To reduce such variations, cell barcoding strategies that enable the combination of individual samples prior to antibody staining and data acquisition on CyTOF are often utilized. The most prevalent barcoding strategy is based on a binary scheme that cross-examines the existence or nonexistence of certain mass signals; however, it is limited by low barcoding efficiency and high cost, especially for large sample size. Herein, we present a novel barcoding method for CyTOF application based on mass ratiometry. Different mass tags with specific fixed ratios are used to label CD45 antibody to achieve sample barcoding. The presented method exponentially increases the number of possible barcoded samples with the same amount of mass tags compared with conventional methods. It also reduces the overall time for the labeling process to 40 min and avoids the need for expensive commercial barcoding buffer reagents. Moreover, unlike the conventional barcoding process, this strategy does not pre-permeabilize cells before the barcoding procedure, which offers additional benefits in preserving surface biomarker signals.

Full textAbstract:
Methods are presented for planning individual catch-sampling, tagging, and field-sampling programs to estimate salmon (Oncorhynchus spp.) harvest in recreational and commercial fisheries from several hatchery-produced and wild cohorts through recovery of coded-wire tags. We show how to determine sample sizes sufficiently large to detect harvest and link sample sizes to expenditures through linear and allometric cost functions to determine optimal tagging and catch-sampling rates. Sample sizes that will minimize bias and variance are charted for field-sampling programs designed to estimate the fraction of a cohort with tags. We describe sampling strategies that can be used to detect or to minimize bias in harvest estimates from tag loss, tag-induced mortality, tag-induced straying, and nonrandom sampling. Methods are demonstrated with data on cohorts of chinook (O. tshawytscha) and coho salmon (O. kisutch) from Alaska.

Full textAbstract:
52 Background: Cancer drug discovery is hypothesis driven focused on addressing specific mechanisms; however the patient’s individual tumor harbor much more diversity and therefore the biomarkers behind the hypothesis are often insufficient in explaining the differences in individual drug response. A Danish Private Public Partnership is developing biomarkers for cancer prognostics under a $30 million grant. The Danish National Biobank was established by another $20 million grant and hosts approximately 15 million biological samples associated with cradle-to-grave electronic medical records. Methods: Proposing a hypothesis-free biomarker-discovery platform using intelligent target-filtering technology integrated with sequencing short reads on a small chip addressing the sample prep and data analysis bottlenecks in current sequencing platforms. By using bioinformatics on existing sequence data it is possible to optimize the proposed strategy and develop novel diagnostic applications. The intelligent target-filtering process generates a single-stranded tag library. Because the tags are single stranded, it is possible to detect all possible tags using a universal high-throughput platform. The cost per sample is low, the content/test very high, and hypotheses free. This approach represents a paradigm shift in the biomarker-discovery process, saving significant time and money while increasing the probability of success. The diagnostic becomes a bioinformatics exercise that allows the drug discovery company to optimize the definition of responders. Results: The result of the digital gene expression experiment was compared to RNA-seq and Affymetrix whole genome array. Conclusions: The platform offers a more cost-effective way of providing an open and hypothesis free platform compared to sequencing. The platform also offers cost-effective open-ended solution for such diverse applications as expression profiling, genome wide methylation profiling, genome wide duplication/deletion analysis, environmental microbiome profiling, and single gene mutation detection with only relatively minor adjustments in how the single stranded tags are extracted from the sample.

Full textAbstract:
High-throughput sequencing technologies are improving in quality, capacity, and costs, providing versatile applications in DNA and RNA research. For small genomes or fraction of larger genomes, DNA samples can be mixed and loaded together on the same sequencing track. This so-called multiplexing approach relies on a specific DNA tag, index, or barcode that is attached to the sequencing or amplification primer and hence accompanies every read. After sequencing, each sample read is identified on the basis of the respective barcode sequence.
Alterations of DNA barcodes during synthesis, primer ligation, DNA amplification, or sequencing may lead to incorrect sample identification unless the error is revealed and corrected. This can be accomplished by implementing error correcting algorithms and codes. This barcoding strategy increases the total number of correctly identified samples, thus improving overall sequencing efficiency. Two popular sets of error-correcting codes are Hamming codes and codes based on the Levenshtein distance.
Levenshtein-based codes operate only on words of known length. Since a DNA sequence with an embedded barcode is essentially one continuous long word, application of the classical Levenshtein algorithm is problematic. In this thesis we demonstrate the decreased error correction capability of Levenshtein-based codes in a DNA context and suggest an adaptation of Levenshtein-based codes that is proven of efficiently correcting nucleotide errors in DNA sequences. In our adaptation, we take any DNA context into account and impose more strict rules for the selection of barcode sets. In simulations we show the superior error correction capability of the new method compared to traditional Levenshtein and Hamming based codes in the presence of multiple errors.
We present an adaptation of Levenshtein-based codes to DNA contexts capable of guaranteed correction of a pre-defined number of insertion, deletion, and substitution mutations. Our improved method is additionally capable of correcting on average more random mutations than traditional Levenshtein-based or Hamming codes. As part of this work we prepared software for the flexible generation of DNA codes based on our new approach. To adapt codes to specific experimental conditions, the user can customize sequence filtering, the number of correctable mutations and barcode length for highest performance.
However, not every platform is susceptible to a large number of both indel and substitution errors. The Illumina “Sequencing by Synthesis” platform shows a very large number of substitution errors as well as a very specific shift of the read that results in inserted and deleted bases at the 5’-end and the 3’-end (which we call phaseshifts). We argue in this scenario that the application of Sequence-Levenshtein-based codes is not efficient because it aims for a category of errors that barely occurs on this platform, which reduces the code size needlessly. As a solution, we propose the “Phaseshift distance” that exclusively supports the correction of substitutions and phaseshifts. Additionally, we enable the correction of arbitrary combinations of substitution and phaseshift errors. Thus, we address the lopsided number of substitutions compared to phaseshifts on the Illumina platform.
To compare codes based on the Phaseshift distance to Hamming Codes as well as codes based on the Sequence-Levenshtein distance, we simulated an experimental scenario based on the error pattern we identified on the Illumina platform. Furthermore, we generated a large number of different sets of DNA barcodes using the Phaseshift distance and compared codes of different lengths and error correction capabilities. We found that codes based on the Phaseshift distance can correct a number of errors comparable to codes based on the Sequence-Levenshtein distance while offering the number of DNA barcodes comparable to Hamming codes. Thus, codes based on the Phaseshift distance show a higher efficiency in the targeted scenario. In some cases (e.g., with PacBio SMRT in Continuous Long Read mode), the position of the barcode and DNA context is not well defined. Many reads start inside the genomic insert so that adjacent primers might be missed. The matter is further complicated by coincidental similarities between barcode sequences and reference DNA. Therefore, a robust strategy is required in order to detect barcoded reads and avoid a large number of false positives or negatives.
For mass inference problems such as this one, false discovery rate (FDR) methods are powerful and balanced solutions. Since existing FDR methods cannot be applied to this particular problem, we present an adapted FDR method that is suitable for the detection of barcoded reads as well as suggest possible improvements.

Mestrado em Bioquímica - Métodos Biomoleculares<br>Antibodies are glycoproteins that belong to the family of immunoglobulins (Ig). They are found in plasma and extracellular fluids of vertebrates and are produced by B cells to identify and to neutralize pathogens and foreign molecules (antigens) in our body. The production of monoclonal and polyclonal antibodies and their ability to bind to a specific antigen, allows their use in quantitative and/or qualitative analyses of specific antigens, in purification methods and in modulating physiological effects in research, diagnosis or therapy. Hen antibodies (IgY) have been studied for such type of applications because they can be produced at a lower cost and in larger amounts. The production of IgY for use in passive immunization has been suggested because there are many antibioticresistant microorganisms, diseases that do not respond to the applied drugs and individuals who are unable to respond to vaccination. The major objective of this work consists on the injection of hens with specific antigens (produced with the aid of fusion tags) which leads to a humoral immune response and to the production of hyperimmune eggs, which were followed a long time. Finally, the stability of IgY was evaluated in aqueous solutions of salts and polymers that could be used in the creation of aqueous biphasic systems for purification purposes.<br>Os anticorpos pertencem à família das Imunoglobulinas (Ig), e que se encontram no plasma e no fluído extracelular dos vertebrados, sendo produzidos pelas células B de modo a identificar e neutralizar as moléculas estranhas e patogénicas (antigénios) ao nosso organismo. A produção de anticorpos monoclonais e policlonais e a sua capacidade para se ligarem a antigénios específicos possibilitou a sua aplicação em análises quantitativas e/ou qualitativas, em métodos de purificação de antigénios e na modulação de efeitos fisiológicos em investigação, de diagnóstico ou terapêutica. Os anticorpos das aves (IgY) têm sido muito estudados neste tipo de aplicações por serem uma fonte mais económica e existirem em maior quantidade. A produção de IgY para aplicação em imunização passiva tem vindo a ser estudada nos últimos anos, e isto deve-se ao fato de existirem muitos microrganismos resistentes a antibióticos, doenças que não reagem aos fármacos aplicados e de indivíduos que são incapazes de responder ao método de vacinação tradicional. Para a produção de anticorpos específicos, expõem-se a ave a um determinado antigénio, através de injeção, levando posteriormente a uma resposta imunitária humoral e assim à produção de ovos hiperimunes. O grande objetivo deste trabalho consistiu na produção de ovos hiperimunes, na qual se acompanhou o perfil dos mesmos ao longo do tempo, seguido da avaliação da estabilidade de IgY em soluções aquosas de sais e polímeros utilizados em sistemas aquosos bifásicos que poderão ser estratégias promissoras para a sua purificação.

Full textAbstract:
<p>The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. A classic chemical analysis involves sampling, sample preparation, separation and detection. In this thesis, an enhanced solid supported microdialysis method was developed and used as a combined sampling- and preparation technique. In general, significantly increased extraction efficiency was obtained for all studied peptides. To be able to control the small sample volumes and to minimize the loss of neuropeptides because of unwanted adsorption onto surfaces, the subsequent analysis steps were miniaturized to a micro total analysis system (µ-TAS), which allowed sample pre-treatment, injection, separation, manipulation and detection. </p><p>In order to incorporate these analysis functions to a microchip, a novel microfabrication protocol was developed. This method facilitated three-dimensional structures to be fabricated without the need of clean room facilities. </p><p>The sample pre-treatment step was carried out by solid phase extraction from beads packed in the microchip. Femtomole levels of neuropeptides were detected from samples possessing the same properties as microdialysates. The developed injection system made it possible to conduct injections from a liquid chromatographic separation into a capillary electrophoresis channel, which facilitated for advanced multidimensional separations. An electrochemical sample manipulation system was also developed. In the last part, different electrospray emitter tip designs made directly from the edge of the microchip substrate were developed and evaluated. The emitters were proven to be comparable with conventional, capillary based emitters in stability, durability and dynamic flow range. Although additional developments remain, the analysis steps described in this thesis open a door to an integrated, on-line µ-TAS for neuropeptides analysis in complex biological samples.</p>

Full textAbstract:
This work is the result of evaluating a novel strategy for the purification of recombinant His-tagged proteins. Proteins purified in this study were the E. coli translational proteins IF-3, RF-1, and RFF. The study aimed to analyse the potential of using Bio-Works WorkBeads™40 TREN, a multimodal anion ion exchange chromatography resin, as a pretreatment step upstream an immobilized metal ion chromatography (IMAC) resin to enhance performance efficiency of His-tagged protein purification. The method demonstrated here shows potential for anyone seeking to increase the purity of His-tagged protein purification or to introduce an effective purification procedure by replacing a polishing step downstream IMAC with WorkBeads 40 TREN upstream IMAC. The latter contributing to guard the IMAC column from heavy bioburden. This study showed that running WorkBeads 40 TREN prior IMAC captures impurities and removes 97-98 % more dsDNA compared to direct IMAC. WorkBeads 40 TREN is therefore highly advantageous to include early in a purification process to remove protein binding DNA fragments. Moreover, WorkBeads 40 TREN increases purity in the final product by capturing more host cell proteins than when running direct IMAC. This concept is general and WorkBeads 40 TREN could be used upstream a variety of resins such as Protein A and RPC.

This master thesis is based on the soil micromorphological study of the sedimentary samples from Anta 1 de Vale da Laje site, located in Tomar, Portugal. The site of Anta 1 de Vale da Laje is one of the sites currently under study within the research framework of the projects Landscape occupation strategies during the Holocene in the Middle Tagus (Es.Ter.Tejo) and Moving tasks across shapes: the agro-pastoralists spread from and into the Alto Ribatejo (MTAS). Asides the stratigraphic problems of the site, it remained unclear the modification successions in time, of the monument and the processes that can be attributed to their sequencing, which were scopes of the abovementioned projects.
Micromorphological study of human impact and natural processes on the environment has been reliant on the interpretation from the study of the undisturbed palaeosols. This study applied the methodological approach of soil micromorphological analyses to understand both the stratigraphic sequence and the evolution of the megalithic tomb of Anta 1 de Vale da Laje site where stratigraphic continuity and discontinuity were observed.
The result of the analyses recognized six (6) periods of activities and three (3) phases of site evolution, as well as identification of human activities relating to agricultural practices, constructions and natural processes such as weathering, leaching, and erosion resulting from impact of rainfall.

Full textAbstract:
碩士<br>國立中正大學<br>化學暨生物化學研究所<br>104<br>In 2006, Yeo et al. applied ac high voltage of high frequency at a corona needle tip to produce ionic wind onto a chip device containing a miniaturized circular reservoir to generate vortex flows. This device can trap and concentrate suspended micron-size particles using micro-centrifugal flows generated by ionic wind. In the thesis, different Surface Enhanced Raman Scattering tags (SERS tags), made of silica-coated gold nano-particle aggregates doped with different Raman dyes is conjugated with Salmonella and Neisseria to be regarded as our experimental samples. Therefore, we would find the lowest limited concentration of Salmonella was concentrated detected by using Raman microscopy to observe when the tag-conjugated bacteria were concentrated in ionic wind driven micro-centrifugal device. When necessary ionic winds were able to dry down small amount samples to further improve concentration effects.
Previously, the micro-centrifugal chips were proved to could trap Neisseria resulting in adequate detections. However, the concentrated Salmonella samples were too dispersed to detect. Therefore we improved the concentration effects by using ionic winds to dry down samples. We found this fast dry-down processes contained three stages to deform and shrink the sample droplet when polystyrene beads of micron sizes were used to observe the microsphere concentration processes. Raman tag-conjugated Salmonella samples of low concentration in deionized water were successfully detected by using Raman microscopy and Gram’s staining method when the samples were dried down with ionic winds.Finally, we investigated the feasibility of this modified device using spiked bacteria samples of various concentrations in pork soup and the drained liquid of washing salad lettuce tag-conjugated Salmonella were successfully concentrated to recognize using Raman scattering signals. On the other hand, the pork soup samples was failed using staining method because of the solution viscosity but staining method still was suitable for lettuce samples.
In summary, this study has improved the ionic wind-driven micro-centrifugal device to develop a fast sample concentration device to detect microorganisms using Raman tags. The preliminary results demonstrate the potential applications in food analysis using this device.

The study of musteloids requires different perspectives and techniques than those needed for most mammals. Musteloids are generally small yet travel long distances and many live or forage underground or under water, limiting the use of telemetry and direct observation. Some are arboreal and nocturnal, facilitating telemetry but limiting observation, trapping, and many non-invasive techniques. Large sexual size dimorphism arguably doubles sample sizes for many research questions. Many musteloids defend themselves by expelling noxious chemicals. This obscure group does not attract funding, even when endangered, further reducing rate of knowledge gain. Nonetheless, passive and active radio frequency identification tags, magnetic-inductance tracking, accelerometers, mini-biologgers and some GPS tags are tiny enough for use with small musteloids. Environmental DNA can document presence of animals rarely seen. These technologies, coupled with creative research design that is well-grounded on the scientific method, form a multi-dimensional approach for advancing our understanding of these charismatic minifauna.

Despite the exponential growth of global hedge fund assets since the 1990s, the high attrition rates in the industry have raised an important issue about hedge fund return persistence. This chapter discusses the various statistical methodologies in measuring performance persistence and provides a comprehensive review of the empirical literature on short- and long-term performance persistence. In particular, the literature suggests that fund strategies and characteristics are related to performance persistence. The chapter also discusses three important issues: return smoothing, the use of option-like strategies, and data biases. The chapter provides additional empirical evidence on performance persistence, using a portfolio approach and a hedge fund sample from the Trading Advisor Selection System (TASS) database between 1994 and 2015.

This article discusses methods that combine survey weighting and propensity score matching to estimate population average treatment effects. Beginning with an overview of causal inference techniques that incorporate data from complex surveys and the usefulness of survey weights, it then considers approaches for incorporating survey weights into three matching algorithms, along with their respective methodologies: nearest-neighbor matching, subclassification matching, and propensity score weighting. It also presents the results of a Monte Carlo simulation study that illustrates the benefits of incorporating survey weights into propensity score matching procedures, as well as the problems that arise when survey weights are ignored. Finally, it explores the differences between population-based inferences and sample-based inferences using real-world data from the 2012 panel of The American Panel Survey (TAPS). The article highlights the impact of social media usage on political participation, when such impact is not actually apparent in the target population.

<i>Abstract</i>.—A feasibility study was begun in 2005 to obtain annual escapement information for sockeye salmon <i>Oncorhynchus nerka </i>over a minimum 3 years, using fish wheels and mark–recapture techniques already employed for Chinook salmon <i>Oncorhynchus tshawytscha </i>since 2001. Failed trials using both traditional spaghetti tags and injected PIT tags led to development of a new type of dorsal tag which which encapsulates a 134.2 KHz PIT tag in the marker of a 70 mm dual-anchor T-Bar tag. This tag was first employed in 2007 to estimate the inriver abundance of Chinook and sockeye salmon returning to the Copper river. For the first sample event, up to three live-capture fish wheels were operated at Baird Canyon for a total of 4,495 h from 18 May to 6 August. During this period, 4,456 adult Chinook salmon and 11,027 adult sockeye salmon were marked. For the second sample event, up to two fish wheels were operated at Canyon Creek near the lower end of Wood Canyon for 3,717 h from 28 May to 19 August. A total of 4,192 Chinook salmon and 56,5511 sockeye salmon were examined for marks. Of these, 459 Chinook salmon and 521 sockeye salmon were recaptures. Using a temporally stratified Darroch estimator, abundance of Chinok salmon measuring 500 mm FL or greater than migrated upstream of Baird Canyon from 18 May to 6 August was 46,349 (SE = 3,283). Using a similar estimator, estimated abundance of sockeye salmon that migrated upstream of Baird Canyon from 18 May to 6 August was 1,290,591 (SE = 92,590). This was the first ever defensible escapement estimate derived for sockeye salmon on the Copper River, and the fifth straight year for Chinook salmon with similar data quality to previous years using traditional spaghetti tags.

Full textAbstract:
In this article we present a new semantic and syntactic-based method for external plagiarism detection. In the proposed approach, latent dirichlet allocation (LDA) and parts of speech (POS) tags are used together to detect plagiarism between the sample and a number of source documents. The basic hypothesis is that considering semantic and syntactic information between two text documents may improve the performance of the plagiarism detection task. Our method is based on two steps, naming, which is a pre-processing where we detect the topics from the sentences in documents using the LDA and convert each sentence in POS tags array; then a post processing step where the suspicious cases are verified purely on the basis of semantic rules. For two types of external plagiarism (copy and random obfuscation), we empirically compare our approach to the state-of-the-art N-gram based and stop-word N-gram based methods and observe significant improvements.

Many online communities use TagClouds, an aesthetic and easy to understand visualization, to represent popular tags collaboratively generated by their users. However, due to the free nature of tagging, such collaborative tags have linguistic problems and limitations, such as high semantic density. Moreover, the alphabetical order of TagClouds poorly supports a hierarchical exploration among tags. This paper presents an exploration to support semantic understanding of collaborative tags beyond TagClouds. Based on the results of the authors’ survey of practical usages of collaborative tags, they developed a visualization named TagClusters, in which tags are clustered into different groups, with font size representing tag popularity and the spatial distance indicating the semantic similarity between tags. The subgroups in each group and the overlap between groups are highlighted, illustrating the underlying hierarchical structure and semantic relations between groups. The authors conducted a comparative evaluation with TagClouds and TagClusters based on the same tag set. The results confirmed the advantage of TagClusters in facilitating browsing, comparing and comprehending semantic relations between tags.

The advent of advanced microscopes; during microscope evolution from simple microscopes to confocal and live cell microscope; having digital imaging facility revolutionized our view for the living cells. In the protein localization study, fluorescent proteins are tagged at amino or carboxyl (preferably) terminal of desired protein for live cell study. These live cell studies improved our understanding of protein dynamics and understanding its role in biological regulation. The mutational variants of fluorescent tags (GFP, RFP); can be used with different protein; which will efficiently use UV-Visible to Far Red light spectrum; without overlapping of excitation and emission spectrum. Further, various cell organelle (Lysosome, Golgi bodies, Endoplasmic Reticulum, Mitochondria, Nucleus) trackers; improved our live cell localization studies in the wide non-overlapping UV-Visible spectrum.This chapter gives an overview for live cell protein localization study in mitotically active, unicellular stage of Dictyostelium discoideum. This evolutionary cutting edge organism had both unicellular as well as multicellular stages during its life cycle. This chapter will provide the design of fusion of fluorescent tag to the specific gene and its live cell localization. Further, it will cover; transformation of the unicellular organism; drug based selection; sample preparation with nuclear, mitochondrial localization markers (trackers) and live cell localization study on live cell-confocal microscope setup. It will also have a glimpse of the design of fusion protein with an aspect of advantage and disadvantages.

Full textAbstract:
A new test technique and apparatus have been developed for measuring the thermoelectric (TE) performance of the quantum well (QW) thin films. Innovative, nanotechnology Si/SiGe QW TE thin film materials have been developed that appear to demonstrate significantly higher Seebeck coefficients and lower electrical resistivities that show the power factor, Seebeck coefficient squared divided by resistivity, to be many times higher than for the state-of-the-art TE materials such as Bi2Te3, PbTe, TAGS or SiGe bulk materials. The power factor values were derived from QW films deposited on very electrically resistive Si substrates. Since the electrical resistance of the Si substrate is so high (> 100 times the QW film sample resistance) it acts like an insulator and the Seebeck and resistivity values that are measured are essentially those of the QW films. The measurement of thermal conductivity of QW films to obtain efficiency and the Figure of Merit, ZT, is much more difficult to measure and spurred this new experimental approach. This test was designed to determine if the QW materials are significantly better in ZT and efficiency than state-of-the-art TE materials such as Bi2Te3. As with the Seebeck and resistivity measurements, the presence of the Si substrate complicates the performance analysis. This test setup was designed to minimize the influence of the substrate. The technique developed allows the N or P sample to be measured as a thermoelectric couple with a copper wire as the other leg. During the test, the electrical output of the test sample and the imposed temperature difference are recorded simultaneously. The measured temperature difference, along with measured electrical properties at the steady-state conditions, is used to calculate the conversion efficiency by two different methods. Three separate QW samples were tested in the new test apparatus. A bulk Bi2Te3 sample was also tested to compare the QW performance with a state-of-the-art bulk TE material. From the experimental data, it was found that the QW samples exhibited conversion efficiencies which were approximately three times higher than the efficiency of the bulk Bi2Te3 material. Also, the experimentally measured properties of the Bi2Te3 sample were in good agreement with the published properties of the material, thus providing additional confirmation of this new test technique. Another confirmation of a higher ZT is that maximum efficiency and maximum power peaks exist at considerably different loads, whereas these peaks both occur near matched loads for Bi2Te3 alloys. The new test apparatus has been used effectively to measure the power factor of the QW thin films deposited on silicon substrates, and this power factor is significantly higher than for the state-of-the-art bulk TE materials.

Pre-trained word embeddings like ELMo and BERT contain rich syntactic and semantic information, resulting in state-of-the-art performance on various tasks. We propose a very fast variational information bottleneck (VIB) method to nonlinearly compress these embeddings, keeping only the information that helps a discriminative parser. We compress each word embedding to either a discrete tag or a continuous vector. In the discrete version, our automatically compressed tags form an alternative tag set: we show experimentally that our tags capture most of the information in traditional POS tag annotations, but our tag sequences can be parsed more accurately at the same level of tag granularity. In the continuous version, we show experimentally that moderately compressing the word embeddings by our method yields a more accurate parser in 8 of 9 languages, unlike simple dimensionality reduction.

Bead and cell suspension based flow-through assays are popular for high throughput biological analysis. Several technologies incorporate a tagging scheme with beads to enable multiplexing. Modern flow-through systems such as flow cytometers and cell sorters are large, bulky and expensive; consequently, much research has been performed using microfluidics to miniaturize these systems. However, several problems remain with these systems, notably it remains difficult to perform manipulations on the beads (or cells), and in the case of multiplexed systems, it remains difficult to read the tags quickly. In this paper, we present a micromachined micro-carrier, referred to as a ‘micropallet’, designed to move through a microfluidic device, which helps to solve several of these problems. Micropallets are small carrier structures, micromachined out of plastic or other materials, that are used to carry attached biological or chemical samples through a microfluidic system (e.g., DNA, RNA, proteins, antibodies, adherent cells, organisms). Similar to conventional factory pallets that carry a product through an automated manufacturing line, micropallets are engineered to carry their cargo through a micro-scale system. Thus micropallets may contain shapes, structures and materials designed to interact with and work in a microfluidic system, such as for docking, sorting, manipulation and readout. Additionally, micropallets may include bar codes or other markings, and be engineered to optimally suit the cargo they carry (for example, a micropallet might contain 3-D structures and treated sections for cells, molecules or organisms to attach). Results are presented for the use of micropallets in cell assays, DNA assays and antibody assays. Micropallets may be designed to carry a sample through a microfluidic system or for use in a static assay system, enabling versatile customisation of the micropallets and flow system for design of a programmable system that interacts with the micropallets for detection, control and manipulation.

Transformer Models have taken over most of the Natural language Inference tasks. In recent times they have proved to beat several benchmarks. Chunking means splitting the sentences into tokens and then grouping them in a meaningful way. Chunking is a task that has gradually moved from POS tag-based statistical models to neural nets using Language models such as LSTM, Bidirectional LSTMs, attention models, etc. Deep neural net Models are deployed indirectly for classifying tokens as different tags defined under Named Recognition Tasks. Later these tags are used in conjunction with pointer frameworks for the final chunking task. In our paper, we propose an Ensemble Model using a fine-tuned Transformer Model and a recurrent neural network model together to predict tags and chunk substructures of a sentence. We analyzed the shortcomings of the transformer models in predicting different tags and then trained the BILSTM+CNN accordingly to compensate for the same.

Full textAbstract:
Abstract We consider the problem of adaptive sampling for global emulation (metamodeling) with a finite budget. Conventionally this problem is tackled through a greedy sampling strategy, which is optimal for taking either a single sample or a handful of samples at a single sampling stage but neglects the influence of future samples. This raises the question: “Can we optimize the number of sampling stages as well as the number of samples at each stage?” The proposed thrifty adaptive batch sampling (TABS) approach addresses this challenge by adopting a normative decision-making perspective to determine the total number of required samples and maximize a multistage reward function with respect to the total number of stages and the batch size at each stage. To amend TABS’ numerical complexity we propose two heuristic-based strategies that significantly reduce computational time with minimal reduction of reward optimality. Through numerical examples, TABS is shown to outperform or at least be comparable to conventional greedy sampling techniques. In this fashion, TABS provides modelers a flexible adaptive sampling tool for global emulation, effectively reducing computational cost while maintaining prediction accuracy.

Full textAbstract:
Fluidic Self-Assembly™ (FSA)™ has become a routine manufacturing process in the production of radio-frequency identification tags. FSA operates through the self-positioning of micro-devices into pre-prepared matching receptor sites in a substrate. Research at North Dakota State University has focused on extending the applications of FSA well-beyond the current production routine. This pursuit requires, among other modifications, substantive extrapolation of the size, depth, configuration, spacing and spatial density of receptor sites. Three different test wafer patterns (see Figure 5 for patterns having nominal sizes of 1050μ, 1500μ, μ2150 and 3050μ square receptors with different spacing between them) took into account the corner compensation structure dimensions, which are based on thickness of silicon mold wafer feature to be etched (see Figure 2). The embossing tool (silicon wafer) was patterned photo-lithographically and subsequently wet etched in a KOH 2:1 solution. Experiments suggest shorter tool life in the case of closely packed features (spacing ~ 0.5mm). Receptor profiles evaluated using both optical and mechanical inspection (see Figures 3 and 4) suggest that features having larger size (up to nominal size of 3050μ square) and thickness (nominal depths of 110μ and 210μ) can be embossed accurately for use in FSA by slightly increasing the embossing time in case of deeper receptors. It was also noticed that the relative receptor depths attained with respect to the thickness of the feature on the mold wafer was lower while embossing deeper receptor sites, leading to the conclusion that mold wafers must be etched longer in such cases. The embossed receptor sites were subsequently filled with micro-devices in accordance with the standard operating parameters of Fluidic Self-Assembly process. These sample experimental runs suggest receptors slightly deeper than the micro-devices facilitate higher yields (or fill rates) in FSA. However, in cases where the receptors are too deep relative to the micro-device (&gt; 5μ), air-entrapment occurred between the micro-device and the bottom of the receptor site, which caused problems in post-FSA processes due to air expansion. This paper presents comprehensive guidelines for embossing larger and deeper receptors for effective use in FSA.
